Class Description
The non-linear phase tap changer describes the non-linear behaviour of a phase tap changer. This is a base class for the symmetrical and asymmetrical phase tap changer models. The details of these models can be found in IEC 61970-301.
Attributes
| Name | Type | Description |
|---|---|---|
| voltageStepIncrement | PerCent | The voltage step increment on the out of phase winding (the PowerTransformerEnd where the TapChanger is located) specified in percent of rated voltage of the PowerTransformerEnd. A positive value means a positive voltage variation from the Terminal at the PowerTransformerEnd, where the TapChanger is located, into the transformer. |
| When the increment is negative, the voltage decreases when the tap step increases. | ||
| xMax | Reactance | The reactance depends on the tap position according to a “u” shaped curve. The maximum reactance (xMax) appears at the low and high tap positions. Depending on the āuā curve the attribute can be either higher or lower than PowerTransformerEnd.x. |
| xMin | Reactance | The reactance depend on the tap position according to a “u” shaped curve. The minimum reactance (xMin) appear at the mid tap position. PowerTransformerEnd.x shall be consistent with PhaseTapChangerLinear.xMin and PhaseTapChangerNonLinear.xMin. In case of inconsistency, PowerTransformerEnd.x shall be used. |
